Solution Overview
Problem
Existing three-dimensional shaping devices that stack layers to form objects face productivity issues due to the time-consuming process of correcting three-dimensional data, leading to decreased quality and productivity of the shaped objects.
Innovation Solution
A three-dimensional shaping device that includes a shaping table, an injecting unit with a heating unit, a moving mechanism, a monitoring unit, and a control unit. The control unit forms layers based on real-time monitoring of a quality control shaped object, ensuring high-quality object formation without the need for data correction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If three-dimensional data correction is performed after shaping an evaluation object, then manufacturing precision is improved, but productivity deteriorates due to the time-consuming correction process
Solution Approach 1:
The patent applies preliminary action by performing calibration shaping before actual production shaping. The control unit stores calibration data obtained from shaping the evaluation shaped object, and uses this pre-stored data to adjust shaping parameters for subsequent production objects. This eliminates the need for time-consuming data correction during production, thereby improving productivity while maintaining manufacturing precision.
Solution Approach 2:
The patent uses the evaluation shaped object as a copy or model to obtain calibration data. By shaping an evaluation object with the same material and parameters as the production object, and using the measured dimensions of this evaluation object to calibrate the shaping system, the patent creates a reference model that guides subsequent production without requiring real-time correction of each production object's data.
2Manufacturing precision
If real-time monitoring and data correction are implemented during shaping, then manufacturing precision is improved, but device complexity increases
Solution Approach 1:
The patent extracts the calibration function from the main production process. Instead of implementing complex real-time monitoring and correction systems during production shaping, the system separates the calibration activity into a preliminary standalone process. The control unit stores calibration results and applies them as pre-adjusted parameters during production, thereby reducing device complexity while maintaining manufacturing precision.
3Manufacturing precision
If evaluation shaping is performed before production shaping, then manufacturing precision is improved, but loss of time increases
Solution Approach 1:
The patent performs the evaluation shaping and data acquisition as a preliminary action before production begins. The control unit stores the calibration data obtained from this preliminary evaluation process, and then uses this pre-acquired data to guide subsequent production shaping without requiring additional time for data correction during production. This shifts the time investment to a one-time preliminary process rather than a recurring production bottleneck.

AI summary
A three-dimensional shaping device that shapes a three-dimensional shaped object by stacking a layer includes: a shaping table on which the three-dimensional shaped object and a quality control shaped object are shaped; an injecting unit configured to inject a shaping material of the three-dimensional shaped object and the quality control shaped object; a moving mechanism configured to move the shaping table and the injecting unit relative to each other; monitoring units configured to monitor a shaping state of the quality control shaped object; and a control unit configured to control the injecting unit, the moving mechanism, and the monitoring units to form the layer. The injecting unit injects, onto the shaping table, the solid shaping material heated into a plasticized state under the control of the control unit, and the control unit forms the layer based on monitoring results of the monitoring units.
